1. DMA module can communicate with CPU through-
   A) Interrupt
   B) Cycle stealing
   C) Branch instruction
   D) Signal sensor
   E) None of these
   
   View Answer

     Option B
   Some Extra:
   In computing, traditionally cycle stealing is a method of accessing computer memory (RAM) or bus without interfering with the CPU. It is like Direct memory access (DMA) for allowing I/O controllers to read or write RAM without CPU intervention.
2. Until a computer can recognize handwriting, an input device must 
   A)  store the information in secondary storage
   B)  optimize the information
   C)  digitize the information
   D)  show the information of the screen
   E)  become an output device also
   
   View Answer

     Option C
   Some Extra:
   Until a computer can recognize handwriting, an input device must digitize the information.
3. NetBIOS is developed by______.
   A)  oracle
   B)  IBM
   C)  Sun
   D)  HCL
   E)  None of these
   
   View Answer

     Option B
   Some Extra:
   NetBIOS (Network Basic Input/Output System) is a program that allows applications on different computers to communicate within a local area network (LAN). It was created by IBM for its early PC Network, was adopted by Microsoft and has since become a de facto industry standard.
4. Virtual memory allocates hard disk space to supplement the immediate, functional memory capacity of what?
   A)  ROM
   B)  EPROM
   C) The registers
   D)  Extended memory
   E)  RAM
   
   View Answer

     Option E
   Some Extra:
   Most operating Systems support virtual memory, which allocates space on the hard disk to supplement the immediate, functional memory capacity of RAM.
5. In MS- Word WYSIWYG stands for______.
   A)  What you see is what you get
   B)  What you see is where you get
   C)  Print
   D)  Preview

   D)  All of these
   E)  None of these
   
   View Answer

     Option B
   Some Extra:
   A dedicated server is a computer running a server operating system housed in a data center. 
8. The definition of thrashing is_____.
   A)  too many processors being managed by the operating system.
   B)  insufficient hard disk space.
   C)  inaccurate information stored in the registry.
   D)  swapping data between virtual memory and RAM too frequently.
   E)  None of these
   
   View Answer

     Option D
   Some Extra:
   In computer science, thrashing occurs when a computer’s virtual memory subsystem is in a constant state of paging, rapidly exchanging data in memory for data on disk, to the exclusion of most application-level processing. This causes the performance of the computer to degrade or collapse.
9. Which of the following ISO level is more closely related to the physical communications facilities?
   A)  Application
   B)  session
   C)  Networking
   D)  Data Link
   E)  None of these
   
   View Answer

     Option D
   Some Extra:
   The data link layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors that may occur in the physical layer.
10. Transmission of computerized data from one location to another is called _____.
    A)  data transfer
    B)  data flow
    C)  data communication
    D)  data management
    E)  None of these
    
    View Answer
